Yes I realised that you do need to manually install the CodeRoad extension into the environment whenever you Rebuild and Reopen a new course. However upon finishing a challenge and trying to start a new one, after I Rebuild and Reopen the container, the CodeRoad seems to save my progress at the end of the previous challenge, and it says “You need to run CodeRoad in a new VSCode window” or something like that (i forgot what it exactly says) and then after trying a new window or quitting + restarting VSCode it still doesn’t work, i needed to clear prune docker’s files and volumes to get it to be able to run like “new”, following the steps you replied to a previous forum post.
So far it is working with a new challenge that I am about to do, and if there are any problems I will highlight it by replying to this forum post.
Thanks for the reply and hope this helps in understanding the problem.
